1'0 all, whom it may concern:

Be it known that I, HENRY Nnwnonsaacifizen of the United Statearesidingalt-Grand Rapids, in the county of Kent and State of 5' Michigan, haveinvented certain new and usefnl Improvements in Carving-Machines; and Ido hereby declare the following to'be a full,

clear, andexact description of the invention, such as will enable othersskilled in the art to I which it-appertains to make and use the same.

My invention relates to improvements in carving-machines; and its objectis to provide the same with certain new and nseful features,

hereinafter more fully described, and partienlarly'pointed 'outin theclaims, reference being had to theaccompanying drawings, in which,

Figure lj'is a side elevation of a device em bodying'my invention; Fig.A, a front elevation of the same; Fig. 3, a plan view of the same, withparts broken away to show the construction; Fig. 4, a detail of theupper part of the machine shown in vertical section on the line 4 410iFig. 2,.and Figs. 5 and 6' 5 details of the head that carries thecutters.

Like letters refer to like parts in all ofthe figures. '1

A represents the stationary frame of; the machine of suitable shape andmaterial tosu'p- 3 p rt the various moving parts. I provide a device onwhich the work is supported, which is both vertically and horizontallyadjustable,

for which purpose B is a vertically-adjusts able bed provided with aseries of detachable bars B, to which the work is secured, any

one or more of which bars.may-be removedto permit a portion of the workto project i downward, as occasion requires. These bars "are also spacedapart to permit inserting bolts 4 or other fastening means between thesame Thesexbars BY tosecure the work thereon.

also attached at the ends to slides B, longitudinally adjustable on thebed B and;con-- 'necte thereto by tongue and groove, whereby the slidesmay be thus adjusted on the frame.

'lhd bed B is mounted updn vertically-slid ingp'osts 15 a and isvertically adjusted by jointed levers it, pivoted at their lowercnds 5.to the frame Aand at theiriupper ends tpithc" cinemasacrame.

bed B and jointed near the middle. These levers are operated byconnecting-rods R, attached to'said levers and to wheels S and S, whichwheels are mounted on a shaft T to rotate in unison and are adjusted bya worm U, 5 5

engaging teeth in the wheel S and rotated by the hand-wheel U'. Byturning this worm the middle joints of. the levers R are all si-.r'nultaneously moved "about the axis of the lower pivotsof the levers,whereby the bed B .60

is raised and lowered at pleasure and maintained at all times in ahorizontal plane.

To simultaneously carve a number of pieces of work and form the same allalike, a series of. spindles C are journaled in a suitable head ,6 5

J, eight being shown arranged in two groups -of four each, and'in thecenter of the head is provided a guide-point C, fixed in the headi andadapted to traverse the-surface of the pattern to the form of which theworkis shaped by the various cutters in the spindles C. u-To rotatethese spindles, I provide twoidrivingshafts D D, arrangedvertically'atthe rear of the head, each having. a keyway, D-", and on;

each shaft 1) is slidably mounted a driving pulley F, having a keyslidably engaging the keyway,-and oneach shaft is also ournaled an armE,to the-forward end of which is pivoted another arm, E, the forward endof'whiehlatter arm is pivoted to the rear of the, head 1 Motion istransmitted from the pulley" F through attached pulleys F and F, jour-fnaled in the aicis of the pivots, connecting. the arms E and E; andattached pulleys F and F, journaled in the axis of the pivots, con-'nesting the arm E" and the head 1, ends se-"w,

riesof belts G, Grfl and G suitably connect the various pulleys. EachbBli/G extends -from a pulley F and engages pulleys F on a. I series offoul-spindles and rotates two of said 9 spindles oppositely to theother'twoto balance the side ..stra'ins of the cutters, and for thispurpose thehbelt extends around theffront of the outer two pulleys ofthe series andthenee around the rear of the, inner twoflpu'lleysoi thesame series, and for the purpose of securing'sulficient frictionalcontact with the lastnamed pulleys said belt G is engaged by id lers F,projept'ing from the front of the head, as v shown in Fig. 3.
